Title: Setter for sintering base plate
Inventor: TODA AKIZO
IPC: F27D3/12
Filed: 1988-05-11
Abstract: PURPOSE:To provide a base plate which reduces the occurrence of warp and a surface crack, by a method wherein a plurality of bridge-beamlike wide grooves are formed in the rear surface of a setter, a plurality of shallow grooves extending at right angles to the wide groove are formed in the upper surface thereof, an intersection point between the two grooves forms a space, and tungsten or molybdenum is used as a material. CONSTITUTION:Tungsten or molybdenum is used as a setter material, and bridge- beamlike wide grooves 11 are formed in the under surface of a setter 10 to allow the enough passage of open air gas through the under surface of the setter. Heat capacity of the setter is decreased to a low value to allow the setter to follow a temperature change in a sintering process. Grooves 12, having width approximate 1/10 that of the groove 11 are formed in the upper surface of the setter, a contact surface between the setter and a ceramic base plate is decreased, and the open air is caused to spread to every corner of the under surface of the base plate. Simultaneous ly, the grooves in the upper and the under surface are intercommunicated to enable the setter to facilitate response to the temperature change of the base plate. The use of the setter provides a ceramic base plate which prevents the occurrence of a surface crack, improves size precision, and reduces the occurrence of warp.

Filed: 1997-04-30
Abstract: PROBLEM TO BE SOLVED: To provide a moving amount detecting device wherein the moving amount of a moving object to-be-measured is detected in real time with high precision. SOLUTION: A measurement device 3 is so allocated as to collimate a center-axis center part of a cylindrical reflection target 2, while a CCD camera 4 is so allocated that the optical axis of the CCD camera 4 agrees with a collimation axis of the measurement device 3. With the direction of horizontal component of measurement device 3's collimation axis as a Y axis, while such horizontal direction orthogonal to the Y axis as an X axis and vertical direction as Z axis, the moving amount in the X axis and the Z axis of the reflection target 2 is obtained by converting the moving amount of the gravity center of reflection target 2's orthogonal projection in the imaged screen of the CCD camera 4 into an actual moving amount, while the moving amount in the Y axis direction is detected based on a distance-difference between a corrected distance which is obtained by correcting a found distance by the measurement device 3 with the moving amount in X axis direction and a measured value in initial state. Then, based on these moving amounts together with a position coordinate of the reflection target 2 in initial state, a current position coordinate of the reflection target 2, or a target object 1, is detected.
